here are 4 PSU's I have compared and they all seem pretty damn good but I don't know which one I should go for,my system uses 690W~ according to pcpartpicker so how much Wattage would I need 750 or 850, btw my gpu is SLI  

[WereCat]

Definitely this one.

The XFX one isnt bad either but it is not necessary unless you plan on 3x SLI which is in my opinion prety pointless as it doesent scale very well in most games at that point.

[Cazzer505]

They are all good but for headroom and future upgrades I would get an 850w psu

The Corsair RM, EVGA  are pretty much the same, so go with the cheapest. If you want to add another GPU later one, go with the XFX.

The other corsair is 80+ Platinum which means that it is more efficient, so that's cool. There's the chance that you will save some money with that one over the years, but it doesn't really matter which one you choose (unless you want to add a third GPU later on).

The Corsair RM 750 seems like a solid choice. I don't know much about EVGA so I really can't really compare them, but I can tell you from personal experience that the RM PSUs are very quiet.

the evga g2 is the best of the bunch.

The RM PSU is made by CWT and uses cheap capacitors. No thank you.

The EVGA is one of the best PSUs out there with the best quality components put together by Super Flower. The XFX is made by Seasonic (also good) and provides 100W more power.

 

If going two way SLI then 750W might be cutting it close with OCing, so the XFX should be the OPs best choice. @JarJarWinker

Evga g2 is a great psu, made by seasonic EDIT: superflower. Xfx is also great and made in 750w, about the Same qualitY, But I don't remember if seasonic or superflower. Sorry I can't see your specs cause I'm mobile.

Another great one is antec hcg series (620, 750, &850 I think) made by seasonic

G2 is made by Super Flower. Sources:  http://www.realhardtechx.com/index_archivos/PSUReviewDatabase.html  http://whirlpool.net.au/wiki/psu_manufacturers

 

It is still the best quality PSU on this list though. The XFX will be a better choice IMO as it's still rock-solid and provides more wattage.

 

(And for some reason whirlpool is not linking but meh)

The XFX Pro Black Edition is a Seasonic G, which is not as good as EVGA G2/Super Flower Leadex.

I think you are referring to the Chicony RMs here, which are now EOL. CWT RMs have Japanese caps on both primary and secondary.

Sorry, I've gotten all discombobulated around the release of the new RM(i)s and old ones.

 

I quite like the new RMs (and their 7-year warranty)! I just really wish that they could have them use Seasonic as an OEM like they did with older models (not RMs, things like the AX non-i and HX non-i) as having an OEM that many people trust is the cherry on top for PSUs. I wouldn't personally spend my own money on any PSU not from Super Flower, Seasonic, or Delta. Just my two cents. I do see though that the new RMi really is quite something, it's just that CWT is a bit inconsistent with build quality at times and I can always lean on the likes of the three I mentioned above for a reliable PSU. 

 

Edit: shuffled words around a lot.

same here, from what i hear/read is that the fan kicks on at a more reasonable temp and it has better volage regs on the 12 volts but i think the 5v was worse. It seemed to be a wash or slightly better. I still have my vote for the evga but, the rm(i) isn't horrible.

Info from Johnny guru, i wish i could open them. Up and test.

It really is very good. I was quiet surprised with how much they improved it and just... well. here. It's a long video: 

TL;DR, it's worth the money.

RMi line is a complete overhaul from the RM non-i. In a nutshell, It is pretty much all the feedback/suggestion we got from you guys when we released the RM. We've tightened the voltage regs, improved ripple and noise suppression, quieter fan operations, longer warranty, etc.. basically all the good stuff the RM has and made it even better, and that how you get the RMi.
